Description
Technical field
The utility model relates to the foam heat-insulating board technical field, and there is the enhancement mode foam heat-insulating board of enhancement layer particularly a kind of inside.
Background technology
Foamed material have the laudatory title of " king of heat insulating material ", is insulated fire sound insulation materials of new generation.Phenolic foam material belongs to the organic rigid foam product of macromolecule, is to be formed by the thermosetting phenolic resin foaming.It has lightweight, fire prevention, chance naked light do not burn, smokeless, nontoxic, do not have drippage, serviceability temperature is enclosed extensively (196 ℃ to 200 ℃), does not shrink under the low temperature environment, the characteristics of not embrittlement.Because the phenol formaldehyde foam rate of closed hole is high, coefficient of thermal conductivity low (can be lower than 0.030w/mk) then, heat-proof quality is good, and has certain water-resistance and water vapour permeability, is heat insulating energy saving material preferably.But it can be molded, also machining, can be made into sheet material, shell and various special-shaped product.It has overcome that original foamed plastics type heat insulating material is inflammable, the shortcoming of thickness, chance thermal deformation, has kept characteristics such as original foamed plastics type heat insulating material light weight, easy construction.At present, in developed country's phenolic foam material development rapidly, fields such as building, national defence, foreign trade, storage, the energy have been widely used in.In the used sound-insulating foamed plastics of U.S.'s construction industry, phenolic materials has accounted for 40%; Japan had set up phenol formaldehyde foam already and had popularized association to promote this new material.Phenolic aldehyde sheet material roughly is divided into the zone face layer, and the zone face layer is two kinds.Mostly surface material is nonwoven, glass cloth, aluminium foil even color steel etc.
As everyone knows, phenol formaldehyde foam is a kind of foamed material of fragility, and therefore, its toughness and flexural strength are relatively poor, is prone in actual use produce embrittlement because of the external force effect.On the other hand, phenol formaldehyde foam has the characteristic of hygroscopic deformation, thereby phenolic aldehyde sheet material in use is prone to because of the moisture absorption of sheet material both sides or water evaporates is uneven causes warpage, brings difficulty and hidden danger to construction.Have both at home and abroad much phenolic foam material is carried out technique for enhancing; Like application number is 200710044879.X, and the Chinese invention patent application that name is called " composite reinforced pnenolic aldehyde foam insulating board and preparation method thereof " discloses the composite reinforced pnenolic aldehyde foam insulating board that a kind of upper surface layer and undersurface layer comprise the enhancement layer that one deck is prepared into by fibrofelt.The patent No. is 201020102563.9, and the Chinese utility model patent that name is called " one step foaming moulding phenol formaldehyde foam honeycomb sandwich composite plate " discloses a kind of two-layer up and down composite plate that is made up of honeycomb core that is full of phenol formaldehyde foam in the cavity and the panel that is attached at the honeycomb core outside.
Prior art mostly is after foam-formed, to add reinforcing material in the outside, but its adhesive property of foam-formed back is very little, so this reinforced effects is not very desirable, and comes off easily.
Summary of the invention
Bad in order to solve the reinforced effects that runs in the above foamed material enhancing, the caducous problem of enhancement layer, the utility model provides a kind of enhancement mode foam heat-insulating board that uses fleece to strengthen at foam inside.
The utility model is realized in the following manner:
A kind of enhancement mode foam heat-insulating board comprises packed layer and one deck enhancement layer at least, and enhancement layer is positioned at packed layer inside.
Described enhancement mode foam heat-insulating board, the enhancement mode foam heat-insulating board set inside that 2-10cm is thick has one deck enhancement layer.
Described enhancement mode foam heat-insulating board, enhancement layer are fleece, and packed layer is a foam.
Described enhancement mode foam heat-insulating board, fleece are jute net or glass fiber grid, and foam is a phenol formaldehyde foam.
Described enhancement mode foam heat-insulating board is characterized in that also comprising upper surface layer that fits in the packed layer upper surface and the undersurface layer that fits in the packed layer soffit.
Described enhancement mode foam heat-insulating board, upper surface layer and undersurface layer are glass cloth, nonwoven, kraft or aluminium foil.
Described enhancement mode foam heat-insulating board, the aperture of fleece mesh or the length of side are 2mm-50mm.
Described enhancement mode foam heat-insulating board, the fibroreticulate aperture or the length of side are 8-20mm.
Described enhancement mode foam heat-insulating board, the fibroreticulate aperture or the length of side are 10-15mm.
Glass fiber grid is the abbreviation of earth grille.Be high a kind of of class in the GSZ.With glass fiber alkali-free roving is primary raw material, and the mesh material that adopts certain weaving to process for the cover glass fiber, improve whole functional performance, forms novel good geotechnological base material through special coated treatment process.Earth grille is former to be a kind ofly to be used for that the road surface strengthens, the old road reinforcement, the good geosynthetics of reinforcing road bed and weak soil base.Handling in the application of asphalt pavement reflection crackle, become irreplaceable material.This product is to process netted base material with high-strength alkali-free glass fibre through international advanced warp knitting technology, the semi-rigid goods of processing through the surface-coated processing.Have through, two-way very high tensile strength of latitude and lower elongation per unit length; And have high temperature resistant, anti-low premium properties such as cold, anti-aging, corrosion-resistant, be widely used in enhancing and railway bed, protecting slope of dam, the airfield runway of flexible pavement, cement pavement and roadbed, object of construction production such as defend and control sand.
Because glass fiber grid has above-mentioned advantage, with foam heat-insulating board compound after, the flexural strength of foam heat-insulating board is increased, the breakage rate of cystosepiment when having reduced construction, and can effectively suppress the warpage of warming plate.
Beneficial effect: the enhancement mode foam heat-insulating board of the utility model; Inside through at foam board increases the fleece reinforcing material, and flexural strength increases, the breakage rate of cystosepiment when having reduced construction; And can effectively suppress the warpage of warming plate, expanded the application of foam heat-insulating board.
